Histogram matching in ANTsR?

[ntustison]

Hey all,

Before I attempt a solution, just wanted to see if the HistogramMatch functionality in ImageMath is available in ANTsR? I didn't see it but wanted to make sure I wasn't missing something.

Thanks, Nick

@stnava --- I think this would be a nice complement to the template-based data augmentation where we not only transform to the reference space but also (optionally, and perhaps randomly) change intensities to the match the reference image.

Not in ANTsR, I usually use https://github.com/Jfortin1/RAVEL/blob/master/R/normalizeHM.R for that.

Thanks John. Good to know there's something out there for immediate processing. Long term, though, will probably look to adding this to the repository.

I think that’s a pretty good idea and now I understand why you want that ... Should be easy to add, going to a wedding tomorrow and then driving Sunday so I may be able to add it over the next few days. will see. Is it urgent?

Also, you might look at deformation simulation Vignette in antsr. same type of idea .

That would be great. No, definitely not urgent. But perhaps I'll try to put something together as a pull request this weekend.

Thanks again, @stnava @muschellij2 . Added it here and currently running. I'll let you know what it does to the results.
